Application filed May 29, 1826. Serial No. 112,635.

This invention relates to new and useful improvements in internal combustion engines, and more particularly to the water jacket connection therefor.

One of the objects of the present invention is to provide such a connecting means, which is of simple construction, consists of minimum parts, and which permits abreaking of the water connection without disturbing the usual rubber hose connection.

Other objects will appear hereinafter.

Figure 1 is an outline view showing a side elevation of an internal combustion engine with a fragmentary section to illustrate the invention.

Figure 2 is a fragmentary top plan view of the engine showing the water jacket connection.

In the drawing:

10 designates the cylinder block, 11 the cylinder head, 12 the crankcase 13 the cooling fan, and 14 the radiator fitted with the rubber hose 15.

According to the present invention, a spout 16 constructed preferably as shown in the drawing has a flat plate and an integral bent nipple, the latter being attached to the end of the hose 15 by a clamping member 17. The cylinder head is formed with an outlet opening 18 which is in communication with the water jacket of' the engine, and over this opening the plate 20 of the said spout is mounted.

The usual cylinder head studs 19 about the port 18 are made somewhat longer than the others and project through apertures in the plate of the spout, and serve to secure not only the cylinder head to the block but also the spout to the cylinder head.

From the above described construction, it will be understood that the following'advantages are secured; first, the radiator connection is capable of being broken without disturbing the hose; second, easy access may be had to the water jacket for purposes of making cleaning the same; and third, a considerable number of parts are saved, as the regular studs used for securing the cylinder head in position serve to retain the water connection in place.

Modification of the above may be made within the spirit and scope of the invention.

What I claim is:

The combination with a cylinder block, of a removable head therefor, registering openings in said block and head for cooling fluid, a member for affording communication between said openings and a radiator, said member formed with a pipe and with a part overlying and closing the opening in said head, and common fastening means for securing said member and said head to said block. a

In testimony whereof I affix my signature.
